What are the classifications of fishing nets?

The common classifications of fishing nets are:? Pull net, drift net, sticky net.

1, pulling the net

Pulling the net, is a large net, mesh about dozens of feet or hundreds of feet long, under the drop, floating on the top. Each end is tied with a long rope. When fishing, one end of the rope is tied to the shore, and then the sampan carries the net and the other end of the rope, spreads the net on the surface, and then leads the rope ashore. When pulling the nets, people stand in two rows and gather the nets together quickly with the trumpet, which is also called "seeing the nets", and it best reflects the spirit of the fishermen's unity and cooperation. Pulling the net is suitable for places where the seabed is flat and the coast is mostly sandy.

2, drift nets

Drift nets, also known as "tie nets", is composed of nets and mango. Mangzi is a thin bamboo pole with a small red and green flag tied to it as a sign, and a large buoy installed underneath. Fishermen go out to sea, usually with a single canopy "foot" boat carrying a lot of nets and mango, fishing, to be under a mango, and then under a piece or several pieces of the net, so that each mango and the nets connected to the piece of the net, the net on the floating, under the fall. After casting the net, the netrope is tied to the boat. The net and the manzi form a net wall in the sea, the fish swims here, often in the net, can't go in or out.

3, sticky net

Not obvious mesh. Fish and shrimp into the mesh, out of the inability to enter, "sticky" on the net. This net is mostly placed in the shallow sea and river ditch. Some fishermen in the winter in order to improve their lives, often set up sticky nets in the field, catching birds of prey to eat. Tianjin wild bird species monotonous, there is only a sand chicken bird, so also known as "playing sand chicken".

Fishing Nets

1, knotting method

is the traditional method of making nets, nets are made of warp threads and bobbins. The fishing net is made of warp threads and weft threads in the shuttle, the knot size is 4 times the diameter of the net rope, protruding from the plane of the net. This type of net is called a knotted net. Knot in the starting net collision fish and boat side, not only hurt the fish and make the net wear, and because of the chemical fiber smooth and elastic, easy to cause knot slack, mesh uneven and other problems.

2, twisting and flicking method

Two groups of yarn by the machine at the same time twisting and flicking, in the intersection of each other through the heart of the intersection into a net, this net is called twisting and flicking knotless net. Because of the net knots at the yarn is not bent, the net flat, reducing friction, but the twisting machine efficiency is low, the preparation process is complicated, the transverse mesh is limited, only suitable for weaving the larger mesh net.

3, warp knitting method

Usually equipped with 4 to 8 comb Raschel warp knitting machine will be connected to the warp yarn into a circle into a net, said warp knitting knotless net. Due to the high speed of the warp knitting machine (600 rpm), the width of the knitted net is wide, and the number of mesh can be up to 800 mesh or more, and it is convenient to change the specification, and the production efficiency is several times higher than that of the previous two methods. Warp knitting knotless nets are flat, wear-resistant, lightweight, structurally stable, with high knot strength, and no deformation or loosening of the nets when they are broken, and can be widely used in sea fishing, freshwater fishing and aquaculture, as well as various other special purposes.
